Quantum-Relativity 101.
Everything in the Universe runs like clockwork, Einstein should have known better than to retain classical units of spatial displacement measurement, within a subject where they are so clearly beyond the scope of their competence. Einstein told himself that he had unlearned everything, well, the poor lad had quite simply forgotten to unlearn the metre.
Footnote 1.
Newton explained that the minus sign
is only required because of the arbitrary choice of the absolute free-space reference platform, but nobody ever bothered to even attend his lectures, let alone actually pay any attention to what Newton actually explained. Newton did explain that with respect to the absolute gravitational origin, everything will be positive of course. Newton also explained that he could not use the absolute gravitational origin because he had insufficient information about the fundamental structure of matter**.
Newton and Bohr, were they both still with us, would each find quantum-relativity both a total breeze to understand and a laugh a minute. Albert Einstein? Hmm, not so much, relatively easy to understand perhaps, but never quite seeing the comical side.
** Well, now we know where the origin is, we still can't use it, so, once again it is; "well-done Newton".
